DescribeZones - Elastic Compute Service

Queries the zones in a specific region.

Operation description

When you call this operation, only a list of zones and some resource information of each zone are returned. If you want to query instance types and disk categories that are available for purchase in a specific zone, we recommend that you call the DescribeAvailableResource operation.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.
